You can workaround this by disabling mprotect via either paxctl -m or chpax -m but it just hides the warning/error so no real solution.I'm not sure whether its BattlEye itself or the ArmA server but I believe its the server..

The second thing is probably related to the mprotect thingy above although it also happens without BattlEye:During shutdown (CTRL+C):
